No gains using pre-increment with -O2

I'm getting results similar although not quite as impressive for the no optimization case. However my results are completely different for the -O2 build showing nearly identical results for post/pre-increment (115.88725s vs 115.80723s). This is on an Intel Xeon 3060 @ 2.4 and linux 2.6.28 with gcc 4.3.3. My best guess is this is due to either a CPU or a compiler difference. It would be interesting to get the specs on the target this was tested on for comparison.
